Since July, Clint Mauldin and dozens of other local and state investigators have been looking into the mysterious disappearance of Rowan County teen Erica Lynn Parsons.

Erica was reported missing nearly a year ago by her adoptive brother, Jamie Parsons, but officials said she had actually not been seen since November 2011.

Her adoptive parents, Casey and Sandy Parsons, have maintained they allowed a then 13-year-old Erica to stay with a woman they believed to be her biological grandmother Irene Goodman, whom they knew as Nan.
